Research And Development On Coal Gangue Lightconcrete Interior Wallboard Series In Steel-structure Residential Building

The steel structure residence as a new style has a wide application prospect. The study aim to steel residence's maintenance system is very few at present.The paper utilizes industrial policy of waste material, developing and popularizing the new-type wall material in a more cost-effective manner, formed the design principle of the standardized board is to the various wallboard system in style, Being based on analyzing and contrasting existing inner wall system of steel-structured residence and from raw material, mixing ratio technique of production and board model etch, this paper researched and developed Coal Gangue ALC Board that represent Coal Gangue light concrete, and getting the sectional form, board type, node of the wallboard of the inner wallboard.The poor sound insulation performance is a main problem in inner wall board field. Dividing a wall into the double-deck is proposed in the paper, which can provide reference for practical project and improve the sound insulation result among households. The most outstanding problem of development of the present new-type wall material is that cracks occur in joint surface between the lightweight wall panel and the solid structure and fractures between the wallboard. According to concept that seam material" the following out of shape and fracture toughness ", the seam measure that Coal gangue light concrete is proposed:1) Adopt polymer modify cement mortar and glass fibre strengthen and lead the measure of compounding;2) Adopt and defend and split the sticky tape;3) Glue the net cloth of glass fibre by a large scale.Finally, the procedure of nodal inner wallboard and shear wall computation is programed, which has certain reference value for engineers and technicians.
